Salts can be easily identified, since they usually consist of positive ions from a metal with negative ions from a non metal. The salt we put on our fries is actually sodium chloride and is made up of metal Na1+ and non metal Cl1- ions. Often you will see this written as Na+ and Cl- (the 1 is dropped) or simply NaCl.
The manufacture of salt is one of the oldest chemical industries. A major source of salt is seawater, which has a salinity of approximately 3.5%. This means that there are about 35 grams (1.2 oz) of dissolved salts, predominantly sodium (Na+) and chloride (Clâ) ions, per kilogram (2.2 lbs) of water.dible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods.
